Yes, there is some concern. The latest git clone from 5.9.0 Paraview does not compile with Qt 5.12. At 92%

QT_INIT_METAOBJECT const QMetaObject QFilterTreeProxyModel::staticMetaObject = { {
There are about 18 such instances of an unrecognized QT_INIT_METAOBJECT in that source file.
This is done in CentOS7 with GCC 7.2.0.
I am testing now if it does compile with 5.15…
Edit: Same issue with 5.15…
